TWO:(1.) Into what two divisions can a knowledge of constructive mechanics be divided?(2.) Give an example of your own to distinguish between special and general knowledge.(3.) In what manner is special knowledge mostly acquired?(4.) What has been the effect of scientific investigations upon special knowledge?(5.) What is meant by the division of labour?(6.) Why have engineering tools been less changed than most other kinds of machinery during twenty years past?(7.) What is meant by machine functions; adaptation; construction?(8.) Why has the name "mechanical powers" been applied to screws, levers, wedges, and so on?(9.) Can power be conceived of as an element or principle, independent of mechanism?
